Strip hinge angle sensor when running a 2.1 HAL as 2.0

VTS ensures that  2.0 HALs don't expose the hinge angle sensor,
but the 2.1 HALs must run 2.0 VTS tests. This CL ensures that
we don't expose the hinge angle sensor on the 2.0 HAL, to avoid
failing those VTS tests.

Bug: 173135479
Test: run vts -a x86 -m VtsHalSensorsV2_0TargetTest
